摘要： The invention concerns a method for monitoring an optical waveguide between a monitoring terminal point and a monitoring unit, in which an optical data signal from a transmitter, and for amplification, pump light from a pump laser, is emitted into the optical waveguide, wherein a monitoring signal transmitted by the monitoring unit is returned via the same waveguide to the monitoring unit by a reflection device located at the monitoring terminal point, in particular a Bragg grating placed in the optical waveguide, and wherein the reflection device is tuned to a reflection that is exactly the wavelength of the monitoring signal, as well as a monitoring system and a monitoring unit for said Method.
